A Brooklyn NYPD sergeant — sidelined after being indicted on charges of making a bogus arrest — is demanding his job back after the key piece of evidence used against him by the department’s Internal Affairs Bureau was found to be trumped up.

Embattled 81st Precinct Sgt. Raymond Stukes was charged with perjury in July 2010 and accused of lying in a signed police report that he’d witnessed a man selling knockoff cigarettes.

Stukes contended that the paperwork the IAB submitted was forged. A Brooklyn judge recently cleared the cop after handwriting experts testified that it wasn’t Stukes’ signature on the papers.

“I’m hoping that the department — in recognition of the errors that led to Sergeant Stukes being wrongly indicted — will restore him to full duty immediately,” said his lawyer, Andrew Quinn, who has sent a letter to Commissioner Ray Kelly with the request.
